Description

Technical Field

[0001] The utility model relates to the technical field related to pipeline anti-corrosion, and in particular to a pipeline anti-corrosion coating device. Background Art

[0002] In order to reduce the corrosion of pipelines caused by the external environment, anti-corrosion coatings need to be applied on the surface of pipelines for anti-corrosion treatment during the production process.

The coating slide rail of the utility model drives the push plate to move, which will push the pipe body to move in the direction of the nozzle, and the servo motor drives the first traction roller to rotate, which will force the pipe body to rotate. The pipe body can move and rotate at the same time, so that the paint can be evenly applied to the surface of the pipe body.

The paint sprayed during the spraying process is also easy to adhere to the equipment. The practicality is poor and needs to be improved. Utility Model Content

[0029] Reference Figures 1 to 4 , which is an embodiment of the utility model, provides a pipeline anti-corrosion coating device, including a coating support mechanism 100, a mobile coating mechanism 200 and an adaptive mechanism 300;

[0030] The coating support mechanism 100 includes a ground base 101 and two groups of first supports 102 and two groups of second supports 103 arranged above the ground base 101. The pipes to be coated are arranged at the top ends of the two groups of first supports 102; the second supports 103 are arranged on the inner side of the first supports 102, and pipe support grooves are provided at the top ends of the first supports 102 and the second supports 103. The coating slide rail 205 is arranged above the ground base 101.

[0031] The mobile coating mechanism 200 includes a nozzle 201, a liquid supply pump 202, a liquid supply tank 203, a second screw 207, a coating slider 204 and a spray hood 208, which are connected to each other through a liquid supply pipeline. The nozzle 201 is provided with two groups, and each group of nozzles 201 is connected with a group of coating sliders 204, and the coating sliders 204 are arranged on a coating slide rail 205. A motor 206 for driving the coating slider 204 to move horizontally is installed on the coating slide rail 205 to provide power; the second screw 207 is rotatably installed in the coating slide rail 205, and the second screw 207 is mechanically connected to the coating slider 204, and the thread structures on both sides of the second screw 207 are opposite; the spray hood 208 is provided with two groups, and the two groups of spray hoods 208 are symmetrically arranged on both sides of the pipeline to be sprayed; the coating slider 204 is provided with two groups, and the two groups of coating sliders 204 are respectively fixed on the two groups of spray hoods 208, and the nozzles 201 are arranged in a ring array on the spray hood 208.

[0032] The adaptive mechanism 300 includes a first support slider 301, a second support slider 302, a first screw 303, a worm wheel 304, a worm 305, a synchronous shaft 306, a synchronous wheel 307 and a synchronous belt 308. The first support slider 301 and the second support slider 302 are arranged on the first support 102 and the second support 103 respectively. The first support slider 301 and the second support slider 302 are each connected to a group of first screws 303; the ends of each group of first screws 303 are connected to the first support slider 301 and the second support slider 302. A group of worm gears 304 are connected, and a worm 305 is connected to one side of the worm gear 304. The worm 305 is fixed on a synchronous shaft 306, and the synchronous shaft 306 is mechanically connected to the motor 206 through a synchronous wheel 307 and a synchronous belt 308; the first screw rod 303 is rotatably arranged in a support slide rail 309, and the first screw rod 303 on the first support slider 301 and the first screw rod 303 on the second support slider 302 have opposite thread rotation directions, and the top of the support slide rail 309 is fixedly connected to the smear slide rail 205.

[0033] When in use, first place the pipe to be coated on the second support 103, then start the motor 206 and the liquid supply pump 202; the liquid supply pump 202 sucks the anti-corrosion paint in the liquid supply box 203 to the spray hood 208, and sprays the paint onto the surface of the pipe through the nozzle 201.

[0034] At the same time, the motor 206 drives the second screw rod 207 to rotate, and the second screw rod 207 is connected to the coating slider 204 through mechanical transmission, so that the coating slider 204 drives the spray hood 208 to move. The threaded structures on both sides of the second screw rod 207 are designed in opposite ways, so that the two groups of nozzles 208 gradually approach each other from both ends of the pipeline until they move to the middle of the pipeline.

[0035] While the second screw 207 rotates, the second screw 207 drives a group of synchronous wheels 307 connected thereto to rotate, which drives another group of synchronous wheels 307 to rotate through the synchronous belt 308, and then drives the synchronous shaft 306 to rotate. The synchronous shaft 306 drives the worm 305 to rotate, the worm 305 drives the worm wheel 304 to rotate, and the worm wheel 304 drives the corresponding first screw 303 to rotate. Since the two groups of first screws 303 have opposite thread rotation directions, the first support slider 301 and the second support slider 302 on the first screw 303 are lifted and lowered in opposite directions, so that the two groups of supports are lifted and lowered alternately to prevent interference with the movement of the nozzle 201, improve the integrity and uniformity of the coating during the moving coating mechanism 200, and improve the practicality and functionality of the equipment.

[0036] In order to improve the drying efficiency of sprayed paint, this equipment can be used simultaneously with drying equipment. After spraying is completed, the sprayed paint can be quickly dried by the corresponding drying equipment.

[0037] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
